ACRs depend on the landing gear geometry (number of wheels and wheel spacing), the landing gear load (that is dependent upon the aircraft weight and center of gravity) and the tire pressure. [ 3 ] Pavement Classification Rating (PCR)
A Boeing 747-400's main landing gear. Note the toes-up bias angle of the bogies on the wing gear, to ensure correct stowage upon retraction: 707, 720, 757, 767, 787: 10 wheels [1x2]+[2x4] A Boeing 757-200 from British Airways: 777: 14 wheels [1x2]+[2x6] A Boeing 777-200 from United Airlines.
The landing gear represents 2.5 to 5% of the maximum takeoff weight (MTOW) and 1.5 to 1.75% of the aircraft cost, but 20% of the airframe direct maintenance cost. A suitably-designed wheel can support 30 t (66,000 lb), tolerate a ground speed of 300 km/h and roll a distance of 500,000 km (310,000 mi) ; it has a 20,000 hours time between overhaul and a 60,000 hours or 20 year life time.

Conventional landing gear, or tailwheel-type landing gear, is an aircraft undercarriage consisting of two main wheels forward of the center of gravity and a small wheel or skid to support the tail. [ 1 ] [ 2 ] The term taildragger is also used.
An aircraft ground carriage (also "ground power assisted takeoff and landing concept") is a landing gear system connected to the ground, on which aircraft can take off and land without their aircraft-installed landing gear. [1] The technical feasibility of the ground carriage is being investigated by two research groups.
The method is also failing to consider accurately the effect of modern landing gear configurations (with multi-wheels arrangements) and the improved characteristics of new-generation pavement materials. As a result, the ICAO triggered the development of a new pavement rating method aimed at overcoming these deficiencies. [9]
The PW800 is based on the Pratt & Whitney Geared Turbofan core without the gear reduction. The departure from Rolls-Royce Aero Engines is rare for Gulfstream. [ 42 ] For the G500 in cruise, at FL400, ISA -5 °C, total fuel flow is 2,920 lb (1,320 kg)/h at M0.90/510 kn (945 km/h) TAS , 2,400 lb (1,090 kg)/h at M0.85/476 kn (882 km/h) TAS. [ 46 ]
